Change tests from "opt %s" to "opt < %s" so that opt doesn't see the input filename so that opt doesn't print the input filename in the output so that grep lines in the tests don't unintentionally match strings in the input filename. llvm-svn: 81537 2009-09-11 20:01:28 +02:00			`; RUN: opt < %s -deadargelim -S > %t`

When DAE drops the varargs part of a function, ensure any attributes on the vararg call arguments are also dropped. llvm-svn: 45892 2008-01-12 00:13:45 +01:00
			`%struct = type { }`
Make DAE not wipe out attributes on calls, and not drop return attributes on the floor. In the case of a call to a varargs function where the varargs arguments are being removed, any call attributes on those arguments need to be dropped. I didn't do this because I plan to make it illegal to have such attributes (see next patch). With this change, compiling the gcc filter2 eh test at -O0 and then running opt -std-compile-opts on it results in a correctly working program (compiling at -O1 or higher results in the test failing due to a problem with how we output eh info into the IR). llvm-svn: 45285 2007-12-21 20:16:16 +01:00

manually upgrade a bunch of tests to modern syntax, and remove some that are either unreduced or only test old syntax. llvm-svn: 133228 2011-06-17 05:14:27 +02:00			`define internal zeroext i8 @foo(i8* inreg %p, i8 signext %y, ... ) nounwind {`
